Patented Apr. 26, 1921.

' To all w from it may concern Be it known that we, Louis C. VAN Pn'rrnwand Join. B. VJOLFE, citizens of the United States, residing at Cheney,in the county of Spokane and State of ashington, have invented certainnew and useful Improvements in Rotary-Rod Weeders, of which thefollowing is a specification.

This invention is a modification and improvement on that rotary rodwecder constituting the specific embodiment of the invention disclosedin our copending application filed May S, 1920, Serial l lo. 379,859,and the present invention primarily has for its object to provide aweeder embodying the advantageous features of our former weederaforesaid with more adequate and easily operated means whereby the hitchmay be so balanced that the tilting lever will not need to be fasteneddown but will stay down without fastening, et when the rod or shoestrikes a rock or other non-yielding obstruction, the resistance causedthereby will be suiiicient to lift the lever until the obstruction ispassed and then the rod and lover will assume their proper places;another object is to provide means wherebythc parts may be quickly andconveniently adjusted so as to vary the depth of penetration of the rodto meet varying conditions of operation and yet maintain the properbalancing of the hitch with relation to the resistance encountered.

The present invention in its detail nature provides for the location ofthe hitch bar behind the main beam to which hitch bar the draft bars arerigidly secured, the latter being hinged to the main beam of the frameto which main beam, and to the auxiliary cross beam that is locatedpreferably between the hitch bar and the main beam, the lifting lever isrigidly secured, the tiller being hinged to the main beam as in the formof our invention set forth in our application aforesaid; there is alsoprovided means whereby draft bars, which are secured to the hitch barmay be held at different angles with relation to the lifting lever so asto adjust the penetration of the rotary rod beneath the surface of theground according to the desire of the operator and also to makeprovision whereby the rotary rod may be held entirely out of the groundduring transportation of the machine from place to place in aninoperative condition.

7 The invention furthermore resides in those novel features ofconstruction, combination and arrangement of parts. all of which will befirst fully describedpthen be specifically pointed out in the appendedclaims and illustrated in the accompanyin drawin s, in which: a

Figure 1 is a perspective view showing the position of the parts whenthe machine is to be transported over the ground in an inoperativeposition.

Fig. 2 is another perspective view of the machine the parts being in theposition shown in Fig. v

3 is a perspective view showing the position of the parts when ready foroperation.

l 1g. lis a perspective view showing the operation of the machine when afixed obstruction is encountered by the rotary rod.

Fig. 5 18 a top plan view of the machine, the parts being in theposition shown in Fig. 2.

Fig. is an enlarged detail section, the parts being in the operativeposition.

Fig. 7 is a similar view showing the parts adjusted to a position wherethe rotary rod will be raised out of the ground. I

In the din-wings in which like numerals and letters of referenceindicate like parts in all of the figures, 1 represents the main beamfrom which the standards l project in the usual manner, and thestandards 4. have the usual bearing shoes 5 for the rotatable rod 6which is driven by the traction wheel 7 through the usual transmissionshaft 8, as has heretofore been the practice. The traction wheel 7 iscarried by the hinged frame 9 which forms an end extension of the beam 1and is held againstelevation above the beam 1 when transporting themachine by cleats 11 passing through apertured members 10 or in anyother suitable way.

12 is the lifting lever which is secured rigidly to the beam 1 and tothe auxiliary cross bar 1 1 which lies to the rear of the beam 1 and isrigidly secured to the beam 1 by suitable braces 15.

The main beam 1, the auxiliary beam 14,
